I have 2 laptops one had Serena and the other had Sonya. There was a minor thing I didn't like about Serena, so I decided to take the plunge and redo both laptops with the newest 18.3 Sylvia. Long story short, I install the OS and 45 updates expecting to get the green check mark. Now systems is blue notifying me that there are still updates, but none of them are automatically selected. I believe they are all level 4. What am I supposed to do here?

I don't understand why the latest LM is requiring some sort of major kernel change or other update?
